Unable to create a row in the snmpTargetAddrTable

Solution In Progress - Updated -

Environment

Red Hat Enterprise Linux 6

Issue

It's not possible to create a row in the snmpTargetAddrTable because the snmpset command throws an error.

Resolution

The issue has been resolved in the following advisory:

net-snmp security and bug fix update

Root Cause

snmpd erroneously checked the length of the SNMP-TARGET-MIB::snmpTargetAddrRowStatus value in incoming SNMP-SET requests on 64 bit platforms, which resulted into snmpd sending error replies to correct SNMP-SET requests.

Diagnostic Steps

Steps to reproduce:

$ snmpset -v2c -c private localhost snmpTargetAddrRowStatus.\'foo\' = createAndGo
Error in packet.
Reason: wrongLength (The set value has an illegal length from what the agent expects)
Failed object: SNMP-TARGET-MIB::snmpTargetAddrRowStatus.'foo'
